DEVICE FOR DISPENSING DRY POWDER A AND DRY POWDER B IN REAL TIME FOR BLOOD PURIFICATION Russian patent published in 2024 - IPC A61M1/16 

FIELD: medical equipment.

SUBSTANCE: invention relates to a device for dispensing dry powder A and dry powder B in real time for blood purification. Device comprises housing (1); two sliding connecting blocks (2) connected with possibility of movement in housing (1). Two sliding connecting blocks (2) are arranged so that contact surface (21) corresponding to the hemodialysis apparatus is located on the sliding connecting blocks (2) rear ends, and preparatory contact surface (22) is located on two opposite face surfaces of two sliding connecting blocks (2). Device has connecting element (3) detachably connected to housing (1); wherein connecting element (3) is located between two sliding connecting blocks (2); one side facing two sliding connecting blocks (2) of connecting element (3) is provided with contact surface (31) corresponding to consumable material. Device includes container (4) for dry powder A and container (5) for dry powder B, wherein container (4) for dry powder A and container (5) for dry powder B are in communication with connecting element (3) by means of a pipeline. Device is configured to feed reverse osmosis water into container (4) for dry powder A and container (5) for dry powder B in order through contact surface (21) corresponding to hemodialysis apparatus, sliding connecting block (2), preparatory contact surface (22), contact surface (31) corresponding to consumable material, and connecting element (3) and the prepared solutions flow in the reverse direction relative to the direction of reverse osmosis water. Device is made with possibility of disconnection of connecting element (3) from housing (1) in such a way that sliding connecting blocks (2) are pressed to each other, preparatory contact surfaces (22) on two sliding connecting blocks (2) are in communication with each other to form a closed loop of contact surfaces.

EFFECT: providing a device for preparing concentrated solution A and concentrated solution B synchronously in real time using dry powder A and dry powder B.
